A right circular cylinder of height 12 cm is covered by
a rectangular sheet of aluminum foil of size 12 cm × 31.4 cm. Calculate the volume of the cylinder.Solution
if tin foil is covered then the curved surface area of cylinder is equal to the area of tin foil. Curved surface area = 16 ×22 H = 16cm Volume = (C.S.A)2 /4 π h = (12×31.4×12 ×31.4×7) /4×22×12 = 20705.16/22  =941.14cm3
